It's frustrating to see so much nationalism in this day and age.
I tried to phrase these questions without snark, but your comment genuinely surprised and confused me. Maybe I'm misunderstanding. I do see how OP's comment is a bit nonsensical in light of the author's Swedish origins, but I don't think this justifies your invocation of a term with such negative connotations.
You’re injecting dismissiveness, again a word with very negative connotation, at a simple mistake.
I would be more inclined to take your point if it wasn’t a cheerful, good-natured attempt at humor - nothing more.
